First Claim
Patent Images
1. A hearing aid for delivering sounds to an ear canal, comprising:
- a coil assembly including a core, a telecoil formed by a first wire wound on the core, and a recharge coil formed by a second wire wound on the core, the first and second wires being separate wires, the telecoil configured to generate a sound signal in response to a sound magnetic field, the recharge coil configured to generate a power signal in response to a power magnetic field;
a processor coupled to the telecoil, the processor configured to process the sound signal;
a receiver coupled to the processor, the receiver configured to deliver the processed sound signal to the ear canal;
a rechargeable battery; and
a charging circuit coupled between the recharge coil and the rechargeable battery, the charging circuit configured to charge the rechargeable battery using the power signal.
